Updating itunes software
If a user experiences this issue they should contact Apple Care.
We still don't know what's causing the problem, as it doesn't appear to be simply user error or oversight.
1) Download Microsoft Program Install and Uninstall Utility from official website. When the install finishes, double-click the icon to run it.
Anytime you update your i Phone, i Pod touch, or i Pad, you will get a new IPSW file that is downloaded to an i OS updates folder courtesy of i Tunes.
Knowing where these files are located can be helpful when troubleshooting and when accessing an IPSW for downgrade or jailbreak purposes.
I only use i Tunes for syncing my i Phone with my Windows 7 PC, so I don't know if a clean install of the new version would get rid of any other errors which might appear when trying to install a new i Tunes over an old one. It runs 5 or 6 additional processes in the task manager and quite a bit of memory even when i Tunes isn't running.
Errors during i Tunes updates have never occurred for me till now, and I hope they won't in future. Is it necessary to have all these processes running when I'm not even running i Tunes?
